Several studies have revealed that COVID-19 is disproportionately impacting men and the potential reasons include everything from biology to bad habits. According to the World Health Organization, men have accounted for 69% of COVID-19 related deaths in Europe. Meanwhile, reports suggest that in New York City men have been dying from COVID-19 at almost twice the rate of women. It is thought that both genetics and lifestyle choices play a part when it comes to COVID-19 outcomes in men. First and foremost, because of their extra X chromosome, women have stronger immune systems and respond better to infections than men. Then there is the fact that more elderly men suffer from heart disease than elderly women and that high blood pressure and liver disease are more prevalent in men too. All of these conditions are factors that are associated with more negative COVID-19 outcomes. In addition, men are statistically more likely to smoke than women. In fact, according to Our World in Data figures, more than one-third (35%) of men in the world smoke, compared to just over 6% of women. With smoking one of the biggest risk factors for chronic lung disease, men are at a much greater disadvantage should they get COVID-19. [Related reading: Can you catch the new coronavirus twice?]
We recently wrote about how avoiding five specific bad habits can significantly extend your life. Now, a new meta-analysis published in The BMJ adds further weight to the argument for eating less salt and being healthier. According to the meta-analysis of 133 clinically randomised trials, lowering salt intake reduces blood pressure – even in individuals who are not yet at risk of hypertension-related conditions. This is important because heart disease is the number one global killer and high blood pressure is the leading cause of heart disease. Furthermore, hypertension is also the leading cause of stroke, heart failure and kidney disease, highlighting how potentially beneficial a low slat diet could be for many people. Interestingly, the research found that the greater the reduction in salt intake, the greater the benefit to blood pressure. At present, U.S. government guidelines advise Americans to not consume more than 2,300 milligrams (mg) of salt per day as part of a healthy eating pattern. However, the vast majority of U.S. adults are eating more sodium than they should -- average of more than 3,400 mg each day. One of the biggest problems is the amount of salt that is contained in manufactured foods, which is usually added to enhance flavour, texture and colour, as well as improve longevity. So even if you don’t reach for the salt shaker at every mealtime, you could still be consuming too much. It’s good to get into the habit of checking the foods you buy to see how much they all contain. After all, just a small reduction could significantly improve your health and reduce your risk of early mortality. Speaking about the findings of the research, lead author Feng He, a researcher at Queen Mary University of London, said: “The totality of evidence in the JACC review and this latest BMJ research shows that reducing our salt intake will be immensely beneficial.”
A new study has revealed five bad health habits which, if avoided, could help you live significantly longer. While the habits themselves are nothing we haven’t heard before, the findings of the study are important as they highlight just how much of an impact the five factors can have on lifespan. So if you want to live years longer, avoid these five behaviours: smoking, not exercising, being overweight, drinking too much alcohol and eating an unhealthy diet. Specifically, the study found that women aged 50 who avoided all five risk factors lived 14 years longer than women who did not. Among men, the difference in lifespan was 12 years. Publishing the study findings in the BMJ, senior author Dr. Frank Hu, who chairs the department of nutrition at Harvard T.H. Chan School of Public Health, said: “We found that following a healthy lifestyle can substantially extend the years a person lives disease-free.” Importantly, the results held true even after adjusting the data for age, ethnicity, family medical history and other potentially influential factors – emphasising that everyone stands to benefit from avoiding these five unhealthy habits. Finally, the research also revealed that the five habits had a positive impact for people diagnosed with a disease during the study period. For example, individuals who developed cancer lived an additional 23 years if they adopted four of the five healthy practices. In contrast, among those who didn't change, half only survived an additional 11 years. The same patterns were witnessed for both heart disease and diabetes.
